[Bug 1938886] Re: rrr:no dh_strip or strip loose setuid bit

[Dimitri John Ledkov]

- objcopy/strip changed in 2.36.1, not keeping file attributes of the
      original file. Work around that in dh_strip to write to a temporary
      file and cat'ing this to the original file to keep the original
      attributes.

which is broken for setuid files.

  I have rebuilt an earlier version of virtualbox, that sets Rules-
  Requires-Root: no and added extra ls statements to find where/when/why
  setuid bits are getting lost after fixperms.

  make[1]: Leaving directory '/<<PKGBUILDDIR>>'
     debian/rules override_dh_strip
  make[1]: Entering directory '/<<PKGBUILDDIR>>'
  ls -latr debian/virtualbox/usr/lib/virtualbox/VBoxSDL

  It seems to me that either dh_strip or something it calls (strip,
  debugedit) looses the setuid permission in hirsute and up.
